Specially designed for Cree XR-E series of LEDs, works also well with other XR types
Lens material optical grade PC with high UV and temperature resistance
(120°C/248°F). Allows use of high current and temperature conditions.
Best available optical efficiency, up to 90%
Very even color distribution over the whole beam angle
Integrated holder. Fastening to heat sink with a PU foam adhesive tape of automotive
grade
We advise customer to ensure the suitability and sufficiency of the bond in the end
product. For example, mechanical stress, vibration and holes on the surface of the
circuit boar weaken the strength of the tape.
Please check fastening details from this link:

*) IMPORTANT NOTICE:
REAL SPOT
lens is a highly efficient pure collimator lens, which optically functions in an
excellent way, giving a high intensity. REAL SPOT lens also reveals the chip level optical
structure of the LED. We recommend REAL SPOT lens for applications, where light
intensity is of highest priority, while we do not recommend it for white light applications,
where color uniformity is of high importance.
SMOOTH SPOT
lens is a pure collimator lens with light mixing properties. It smoothens
the beam pattern and makes a uniform color distribution over the whole beam angle. Light
intensity is lower than for the REAL SPOT lens. SMOOTH SPOT lens is recommended for
white light applications, where pleasant, high-quality illumination is wished.
